Americans have a very short memory. Next to Pearl Harbor 911 was the worst attack ever to the USA. 911 was unparalled, as we were not at war. The lost of life and injuried was over 3,000 and I still remember people jumping out of windows to escape being burned to death. So I must say 911 was so big, we must never forget. Boston was also, a surprise terrorist horrific attack.How could anyone place a bomb next to an 8 year old boy.This event was equally as bad, but we were lucky not as many killed and injuried. We got Bin Laden, shut down the transfer of most funds to Terrorist, now they are smart enough to recruit, and brainwash people in the USA to be terrorist. We live in a different world these day's and must adapt, like Israel has done, to be aware of potential problems, which will cause us to give up some of our casual freedoms, like sporting events, long lines being checked. Like our airport rules. My heart goes out to all families and friens of both the 911 event, and the Boston event. We must never forget, and do everything possible to beef up our awarness, so it reduces the chance of happening again.
